php - Can't separate cells properly with simplehtmldom

I am trying to write a web scraper. I want to get all the cells in a row. The row before the one I want has THOROUGHBRED MEETINGS as its plain text value. I can successfully get this row. But I can't figure out how to get the next row's children which are the cells or tags.

if ($foundTag = FindTagByText("THOROUGHBRED MEETINGS", $html))
{
    $cell = $foundTag->parent();
    $row = $cell->parent();

    $nextRow = $row->next_sibling();
    echo "Row: ".$row->plaintext."
\n";
    echo "Next Row: ".$nextRow->plaintext."
\n";
    $cells = $nextRow->children();

    foreach ($cells as $cell)
    {
        echo "Cell: ".$cell->plaintext."
\n";
    }
}


function FindTagByText($text, $html)
{
    // Use Simple_HTML_DOM special selector 'text'
    // to retrieve all text nodes from the document
    $textNodes = $html->find('text');
    $foundTag = null;

    foreach($textNodes as $textNode) 
    {

        if($textNode->plaintext == $text) 
        {
            // Get the parent of the text node
            // (A text node is always a child of
            //  its container)
            $foundTag = $textNode->parent();
            break;
        }
    }


    return $foundTag;
}

Here is the html I am trying to parse:
